冲刺四季度一线见闻丨让黑色焦炭产出更多绿色氢能Insights from the Frontline Sprinting into the Fourth Quarter | Let Black Coke Produce More Green Hydrogen

According to Hebei Daily, on November 5, 2026, at Dexin Hydrogen Energy Technology (Hebei) Co., Ltd. in Shexian, Handan, the person in charge, Tan Xiaoliang, was discussing coke oven gas supply cooperation with representatives from a coking plant. They communicated about how much standard cubic meters of coke oven gas the coking plant could reliably supply each year after the gas supply pipeline is connected, providing raw material assurance for the expansion of the integrated hydrogen production and utilization project from coke oven gas.

The first-phase production line of Dexin Hydrogen Energy's integrated hydrogen production and utilization project from coke oven gas has now entered a stable operation phase, capable of processing 15,000 standard cubic meters of coke oven gas per hour, with an average daily hydrogen output of about 7 tons. Focusing on achieving fourth-quarter objectives, the company is making every effort to expand coke oven gas supply channels, aiming to further increase hydrogen production capacity by the end of 2026 and lay the groundwork for the commencement of the second-phase project next year.

Walking through the 132-acre factory area, the workshops as well as the coke oven gas compression and boosting equipment, purification devices, and PSA (pressure swing adsorption) hydrogen production units are arranged in an orderly manner, and the first mature and complete coke oven gas hydrogen production line is fully operational. "After the coke oven gas enters the plant, it goes through multiple processes such as compression, purification, and pressure swing adsorption to extract and purify hydrogen. The annual hydrogen production of the first phase of the project reaches 29.38 million standard cubic meters," said Tan Xiaoliang.

Dexin Hydrogen Energy is a wholly-owned subsidiary of Delong Steel Group. Aligning closely with the "dual carbon" development goals, the company, leveraging the relatively abundant coke oven gas resources in Shexian County, has launched a comprehensive utilization project for hydrogen production from coke oven gas, producing green hydrogen from black coke and promoting the industrial chain towards the green and low-carbon field. Hydrogen accounts for about 60% of coke oven gas. The company uses PSA hydrogen extraction technology, which separates hydrogen from coke oven gas based on the differential adsorption characteristics of the adsorbent under different pressures, ultimately obtaining high-purity hydrogen with a purity of up to 99.999%. With advantages such as low investment, low energy consumption, and a short process, the high-purity hydrogen produced by the company has strong market competitiveness.

With stable production capacity, Dexin Hydrogen Energy is now focusing on connecting the hydrogen energy market application chain and expanding the external sales range of high-purity hydrogen. Inside the hydrogen refueling station within the plant, multiple long hydrogen tube trailers are undergoing hydrogen filling operations, with a staff member on duty throughout, closely monitoring the equipment's operating status to ensure safety and order. Tan Xiaoliang told reporters that the produced high-purity hydrogen is compressed by a diaphragm compressor into the long tube trailers, transported to hydrogen stations and enterprises in electronics, food, and other industries, and can also meet hydrogen needs for scientific experiments.

Currently, the company is actively developing green logistics, extending the hydrogen sales market outward. By the end of November 2026, this expansion will reach a 200-kilometer radius, north to Huanghua Port in Hebei, south to Anyang in Henan, west to Changzhi in Shanxi, and east to Rizhao in Shandong. The implementation of the coke oven gas-to-hydrogen comprehensive utilization project helps the company build a full hydrogen energy industry chain of 'production, storage, transportation, use, and research,' accelerating the development of the green low-carbon industry. According to statistics, the company annually fills 720 tons of hydrogen for hydrogen-powered heavy trucks, achieving an annual reduction of 8,180 tons of carbon dioxide, thereby reaching the dual goal of ecological and economic benefits.

Rushing into the fourth quarter, efforts are being made simultaneously in project construction and market expansion. Moving forward, the company will focus on the development goals of the entire hydrogen energy industry chain, continuously deepen its industrial layout, explore new hydrogen storage models, and further reduce transportation costs and expand sales markets through innovations in storage and transportation technology, injecting strong momentum into the high-quality development of the local renewable energy industry and the green and low-carbon transformation of industry. According to the plan, once the second and third phases of the project are fully completed and put into operation, the company's total hydrogen production capacity will achieve a fourfold increase.
